There are many factors that contribute to the onset of wrinkles. The following are the Four Main Reasons that Cause Wrinkles?

Wrinkles are a normal part of the ageing process. Skin cells divide more slowly as we age. The dermis, or the inner layer of skin, begins to thin. The elastin and collagen fibre network that supports the outer layer loosens and unravels. This procedure causes depression on the skin's surface. Skin becomes more fragile as we age. Furthermore, oil-secreting glands are less efficient, causing the skin to retain less moisture and appear wrinkled. All of these elements contribute to the formation of wrinkles.
FACIAL MUSCLE CONTRACTIONS
Lines between the brows ("eleven" or frown lines) and lines extending from the corners of the eyes (crow's feet) are thought to form as a result of underlying muscle contractions. These wrinkles become more prominent with age as a result of habitual facial expressions such as smiling, frowning, squinting, and others. The expressions, together with gravity and the loss of underlying bone and fat mass, contribute to the formation of jowls and drooping eyelids over time.
Healthy skin regenerates on its own. New collagen is being produced and installed while old collagen is being broken down and removed. Researchers discovered that smoking tobacco products reduce the production of new collagen. Wrinkles appear as a result of a lack of new collagen. This could also be due to a lack of blood supply to the skin as a result of smoking.
Excessive exposure to ultraviolet radiation (too much sun) can cause photoaging, or premature ageing of the skin. UV rays from the sun cause photoaging, which damages collagen and elastin fibres (the major structural proteins in the skin) (the protein that enable skin to stretch). Both of these fibres are important components of the connective tissue of the skin. Without them, the skin loses its elasticity and strength, resulting in wrinkles. Certain enzymes are produced when ultraviolet light damages skin tissue. These enzymes are responsible for the formation and reformation of collagen. However, some healthy collagen fibres are damaged during the process, resulting in a disorganised formation of fibres known as solar scars. When this rebuilding process is repeated, wrinkles form.
